By definition amplitude is simply the maximum distance from the zero or neutral position of the wave. NOTE: As a distance, amplitude is an absolute value, there will be no negative amplitudes.
EX: A simple sine wave might have the form y = A sin(theta(x)) where theta(x) = 0 to 360 deg at x and y is the YY axis displacement of a wave along the XX axis. A is the amplitude. As you can see when theta = 90 and 270 degrees, y = A and - A. The absolute y value can't get any bigger than A so that's the maximum absolute value. So the amplitude is reached at those angles.
Amplitude is an important factor in wave related physics. For example, it can be shown that the energy contained in a wave is proportional to the square of its amplitude. And that makes sense as the bigger the wave (the bigger amplitude) the more energy it would contain is intuitively logical.

What is the meaning of AM in radio wave?
amplitude modulation
How does intensity work?
In general, intensity refers to the amount of energy or power carried by a wave. In the context of sound and light, intensity is proportional to the square of the amplitude of the wave, meaning that doubling the amplitude increases the intensity by a factor of four. Intensity is measured in watts per square meter.
What does the energy of a mechanical wave depend on?
In fact, energy of the wave is one interpretation of a wave's amplitude. Many versions of amplitude exist. If amplitude has a specific meaning and a specific unit...it needs to be specified. Some examples are displacement amplitude, energy amplitude, pressure amplitude, restoring force amplitude, intensity, decibel level, etcetera.
What does the period vs amplitude graph reveal about the relationship between the two variables?
The period vs amplitude graph shows that there is no direct relationship between the period and amplitude of a wave. The period and amplitude of a wave are independent of each other, meaning changes in one variable do not necessarily affect the other variable.
What is the meaning of the natural frequency of a body?
The Natural frequency is the frequency at which Resonance(maximum amplitude) occurs.
What is A waves capacity to do work?
The capacity of a wave to do work is determined by its amplitude. A wave with larger amplitude carries more energy and thus has a greater capacity to do work. The energy of a wave can be transferred to other systems to perform work, such as causing objects to move or creating vibrations in a material.
What is the meaning of AM in the wave length?
AM stands for Amplitude Modulation, which is a method used to encode information onto a radio wave by varying the strength (amplitude) of the wave. In terms of wavelength, AM refers to the distance between two consecutive crests or troughs of a wave.
What do you call Points of maximum amplitude on standing wave?
Points of maximum amplitude on a standing wave are called antinodes. These are positions along the wave where the amplitude is at its maximum, meaning the oscillations are at their peak. Antinodes occur at locations where constructive interference happens, resulting in a stronger wave.
What the meaning of suspected right hypertrophy low QRS amplitude probably abnormal ECG?
probably abnormal ECG?
How are the amplitudes of sound waves?
There is not only "one" amplitude. There is an amplitude of particle displacement ξ, or displacement amplitude, an amplitude of sound pressure p or pressure amplitude, an amplitude of sound particle velocity v, or particle velocity amplitude, an amplitude of pressure gradient Δ p, or pressure gradient amplitude. If the "sound" inceases, the "amplitude" also increases.
A sound waves amplitude corresponds to the sounds what?
Usually, people are asking as if there is just "the" amplitude in sound waves in air. The loudness perception of a sound is determined by the amplitude of the sound waves − the higher the amplitude, the louder the sound. Which amplitude of sound (sound amplitude) do you mean? There are: amplitude of particle displacement ξ, or displacement amplitude amplitude of sound pressure p or pressure amplitude amplitude of sound particle velocity v, or particle velocity amplitude amplitude of pressure gradient Δ p, or pressure gradient amplitude. Furthermore, think of the amplitude of the oscillation of a string. The maximum magnitude of the deflection of a wave is called amplitude. Look at link: "What is an amplitude?"
What kind of amplitude does a quiet sound have?
A quiet sound typically has a lower amplitude, meaning that the sound wave has a smaller peak-to-peak distance or intensity. This results in a lower volume or energy level compared to louder sounds.
